Two route based vpn's over the same phase 1

Is it possible to have multiple phase 2 tunnels running over the same phase 1? My case is that i have two firewalls with multiple VR's and I would like to created a route based VPN between all the VR's. The two firewalls are connected to each other via one public IP on each side so I would essentially ahve one phase 1 setup with mulitple ST0 interfaces terminating in different VR's

As you can see below I tried to make one ike gateway then have two vpn's reference it. It seems to work for a few minutes then only one of them remains up and the other goes down.
